We felt motivated by the observation
that the fairly complicated CHSP-related mathematics
weakened the appeal and
visibility of the innovative methodical aspects of the approach
[1]}.
For this reason,
the current return of attention to the physics with
non-Hermiticites [2]} was obviously
motivated by the
simplification of some technicalities
provided by the most popular PTQM philosophy [3]}, [4]}.
